Sudoku Daily Grid · Last updated: 8 September 2026
Published by Yumeng Tang
Sudoku Daily Grid (“the App”) is a daily Sudoku game for iPhone. It does not require an account, and we do not operate a gameplay server.
Summary
- No sign-in. Streak and completed days stay on your device.
- The App does not currently show ads or use analytics SDKs.
- Subscriptions are billed by Apple. We never see your card or Apple ID password.
Data stored on your device
The App uses on-device storage (UserDefaults) for:
- Whether today’s Classic and Mini are finished
- Streak count
- Whether a Subscriber subscription is active
This data is not synced to our servers. Removing the App deletes it.
In-app purchases
Subscriber (monthly or yearly) is processed by the Apple App Store under Apple’s Standard EULA. Apple may share purchase status with the App so we can unlock the archive, Auto notes, and unlimited Check and Hint.
Children
The App is not directed at children under 13. We do not knowingly collect personal information from children.
Changes
We may update this policy. The “Last updated” date at the top will change when we do.
